SUMPRODUCT Formulas Slowing Worksheet Significantly

Jan 22, 2009

I have had a workbook that I have been using to track inventory. I use a userform to enter the data for inventory in and out of the system. I recently added two more worksheets to the workbook, each of which has several SUMPRODUCT formulas on them that reference the inventory data.

Since adding these two sheets, when entering data via the userform, it takes a long time (relatively speaking) for the sheet to update with the relevant new data. I have attached a copy of the file, in hopes that someone can show me exactly what is causing the slow-down, and if there is a way that I can get the same results using different programming or formulas that will not be so slow.

The part that is slow is on the "Data" sheet. Click on the green or orange buttons to open the userform. Make a selection in each section, and enter an amount. Clicking on "Enter" will transfer the appropriate information to the worksheet. This is the part that is slow.

SUMPRODUCT Formulas Slowing Down Calculations

Feb 22, 2008

I am doing a report which analyzes a specific person's transaction per country (3 criterias). The workbook has 3 sheets. First sheet is the database, 2nd is the report itself and 3rd is a reference table. I am using a sumproduct formula to count per person's transaction per country. It is giving me slow calculations.

I cannot possibly use a pivot table since there will still be other calculations involved after determining the transactions. I tried using database functions but i can't seem to understand how to go about it when there are multiple criterias involved.

I am attaching a sample file for your reference.

Sumproduct Usage Slowing Down Spreadsheet

Sep 25, 2009

My spreadsheet has a sheet1 with 1000 rows and needs four columns with "sumproduct" formulas referencing sheet2 with 20000 rows. An example of the formula is:

=SUMPRODUCT(--(Sheet2!$F$2:$F$20000=$B3),--(Sheet2$A$2:$A$20000 >=$J$2))

Once I add them, the recalculation slows it to a crawl. In trying to understand the problem, I do a Manual/Automatic between running a sort. The recalculation still takes too long to be practical.

Formulas Are Slowing Sheet Down

Feb 18, 2008

I have a spreadsheet that has 1800 sumproduct formulas in it. Foe each day of the year it counts or sums 5 things. Each of these things has 2-3 criteria that is why I used sumproduct. The database it counts from is on the same sheet. It takes to long for the sheet to calculate. Is there a better way. I am using Excel 2003. The sheet itself is not huge 913 kb.

Too Many Sumproduct Formulas Causing Slowdown

Aug 27, 2009

I want to say thanks for any help you might be able to offer. Attached are 2 sheets out of a workbook I am using which has many sumproduct formulas. On the the Input sheet, is where vacation and training forecast dates are listed. On the Calcs sheet, there are 2 monthly calendars for the year, 1 for vacation, the other for training. Would like to know if there is a way to have both records show up on only one calendar set. I currently have the vacation shown as a '1' and the training shown as a '9'. The workbook is used in Excel 2003 & 2007.

Summarizing Data With Vlookups Or Sumproduct Formulas

May 19, 2007

I've got a tab with 32K+ lines of data in six columns. I need to be able to summarize it in a table based on two criteria (e.g. Region, Line of Business). I am currently using 16 sumproduct formulas (=sumproduct((type=a5)*(reg=a4)*revenue)) where type is the line of business and reg is the region column, and 8 vlookups per region. Each tab will have about 8 regions and I'll have 4 tabs. As you can tell, this spreadsheet will quickly get out of hand in terms of calculating speed. I can't really use a pivot table because of: 1) formatting constraints 2) the vlookups refer to a separate tab than the main data dump. What alternatives do I have other than array formulas to get the data in a nice little summary form? The formulas/presentation aren't very complicated, but I have yet to come up with a good alternative to the above.

Copying Sumproduct Formulas Between Worksheets Causes Errors

Oct 19, 2007

I was kindly provided with a formula from this forum a few months ago (in the attached workbook) to calculate the area under the curve of strings of data of varying length (i.e. different number of rows) these strings of data are aligned with a timeline (providing the Y and X axis for the curve respectively). The formula is able to calculate the area under these curves without the need for adjustment to the number of rows of the dataset.

However I have now tried to copy this formula to a new datasheet with a different total number of rows and a timeline fixed (of different intervals) in column A (rather than moving for each string of data) and I am receiving a #N/A error. I am sure that I have copied the formula correctly. Can anyone help fix my formula so that it calculates area under the curve again? I would like it to calculate the area under the curve for the data in the same column but using the fixed timeline in column A.

The working formula is on the sheet ‘original formula layout’ and the formula containing the error is on the sheet ‘new formula layout’.

Database Functions Vs. Array Formulas Vs. SUMPRODUCT Vs. Pivot Tables

Dec 13, 2006

All I am doing is counting text values in a table.

The table has 3 main columns(which are relevant to this thread anyway).

Shift - Area - Status

The example I have attached shows examples of DCOUNTA, SUMPRODUCT and a Pivot Table.

I have read many threads stating that the best one to use is Pivot Table followed by DCOUNTA followed by SUMPRODUCT.

The most effective for me seems to be SUMPRODUCT (although this does slow excel down dramatically when you use a lot of these formulas). As do Array Formulas

The Pivot Table does not update on its own, therefore constantly needs to be refreshed. (I could use code to do this)

The DCOUNTA seems to be the least effective at doing what I want (unless I am doing something wrong)

In the attached example can the DCOUNTA be used more efficiently as I don't like the fact that I am duplicating rows to apply the criteria for a different shift. e.g

Area 1 - Late Shift - Banned
Area 1 - Early Shift - Banned

I want my table to be as follows (as the SUMPRODUCT shows)

AREA - Early Shift - Late Shift - Night Shift - Area Total
Area 1
Area 2
Area 3
Area 4
Area 5

Shift Total

Vlookup Slowing Down Workbook

Jun 28, 2007

I would like to make a file that can calculate the quantity that need for the bakery shop, it's just my example. The customers can order the number of layers of the cake and that is related to the quantity from the table. I would like to looking for the 3 ingredients and the quantity in grams, and afterwards create a pivot table to sum by each type of the ingredients. The orders is about 3000 rows and ingredients are about 20 columns, If I use IF() and Vlookup() or put in Array formula, my program will be very very slow. Can I use others function to get the ingredients and the quantities? I have attached the file belows.

Please also make some suggestion, or something to read more, about the way I use the funtion like I use IF()+IF() or IF()&IF() instead of IF(,,IF). Does it make any different?

Slowing Down And Waiting For Data Results Using VBA?

Aug 21, 2013

I have 2 sheets in a workbook

My VBA code gets data from a cell in sheet1 Then it paste that into a cell on sheet2 sheet 2 processes some data and produces a single cell result based on the pasted data Then that single cell result is pasted back into sheet1

Here is the problem. Sheet 2 takes a up to one second to produce the final result because it has to fetch some data from the web My code is pasting data back to sheet1 before sheet2 has had time to produce a final result

How can I make sure the data is finished on sheet2 before my code paste the result back to sheet1?

The variable MacdBlack is the being pasted back to sheet1 before sheet2 has had time to update it This is because sheet2 has to get data from the web which is slow

VB:
Sub SheetTest()
Dim x As Integer
Dim StartCell1 As String

[Code]....

Offset Index Match Formula Slowing Down Excel

Dec 28, 2009

I have the following formula in a cell:

=SUM(OFFSET(INDEX(J:J,MATCH(9.99999999999999E+307,J:J)),0,0,-M9))/M9
When the workbook with this formula is open it slows down other workbooks quite a bit.

If I run code in another workbook without the workbook with the formula open, calculation takes 0.099 seconds. If the workbook with the formula is open, the same code takes 2.24 seconds.

How could I change/replace above formula to average the last n (cell M9 value) cells in an ever changing column.

Copy Worksheet To New - No Formulas

Dec 19, 2008

starting to dabble in the VBA coding, now. I tried finding this solution...but nothing quite the same. I have a spreadsheet with a couple tabs. The main tab is a calculation worksheet that pulls in, and performs various calculations on, data from the other couple tabs. This main tab will be the only one that most of my users will see (query and other data tabs will be hidden.)

What this workbook does is calculate accruals for our consultants, at the end of every month (period.) I am trying to put in code that, when activated by a button, will copy the entire main ("Accrual Worksheet") tab as a new tab, at the end of the workbook....as a period backup to the calculations on the main tab.

I created the below
===========================================================
Private Sub CommandButton2_Click()
Dim LastSheet As Integer
Dim aSht As Worksheet
Dim Test4 As String
Dim NameXists As Long

If MsgBox("Are You Sure You Wish to Finalize? This will copy sheet, without formulas, as backup.", vbYesNo, "Update Confirm") = vbNo Then
Exit Sub
Else

=============================================================

This seems to work great......EXCEPT (you knew one was coming), I only really want to copy the sheet as data/format only. I don't want the copy tab to have any VBA code, or formulas, on it. I just want a picture image of the "Accrual Worksheet", as reference to the activity for that period. In the following period, the same "Accrual Worksheet" will be used to work on the next month's activities.....and the data on that tab will change. So we need to store the final calculation, for further reference.

Deleting Worksheet Causes #REF! In Formulas

Sep 4, 2006

I have a macro that imports a text file. I then have summary sheets that reference to the sheets with the imported text file details. This is a task I complete every month.

The next month I delete the sheets with the imported text file details before importing current month's details. But when I do that it screws up my references.

Here's an example of a reference with previous months' imported text file details:

= SUM('X'!$I$1:$I$3000)/2+SUM('Y'!$I$1:$I$3000)/2

When I delete the sheets with the imported text file details and import current month's details, my reference suddenly looks like this:

=SUM(#REF!$I$1:$I$3000)/2+SUM(#REF!$I$1:$I$3000)/2

What can I do to prevent the summary sheet from messing up my original references?

Insert Worksheet With Formulas

Dec 19, 2007

I have a workbook with a worksheet called Summary that has formulas that refer to other worksheets (say A, B, and C) in the same workbook.

What I want to do (with VBA because I have to do this many times) is copy this Summary worksheet into several other workbooks, all of which also have their corresponding worksheets A, B, and C.

I do *not* want the copied Summary worksheet's formulas to refer to the old workbook. If I copy the worksheet by hand, this is what happens.

Instead I want the copied worksheet's formulas to reference the worksheets of the workbook they are now in.

Entering Duplicate Formulas From Different Worksheet

Jul 21, 2009

Basically I have a template from two different worksheets and I am making one sheet the "master sheet" and the other sheet is filled in automatically from the master sheet. I understand how to get this basic function to work so here is my real problem...

I would like my sheet to look like this repeated 2000 times...

'sheet1'A16
'sheet1'A16
'sheet1'A17
'sheet1'A17
etc.

Every time I try to drag the formulas down to go 2000 rows it starts doing this...

'sheet1'A16
'sheet1'A17
'sheet1'A18
'sheet1'A19
etc.

How do I get this formula to repeat like I have shown in my desired example?

Split from Copy, Cut, Fill Relative Or Absolute Formulas

If you "cut", rather than copy, Excel will maintain the original cell references in the formula.

Both of these questions are well within the experience level of a user with above average skill level as your profile shows. Please lower it (before one of the Admins does it for you) to a more realistic level.

See this training page on how to toggle between relative/absolute cell references: [url]

Well cutting is a nifty trick, thank you for that, I don't believe you quite understood my first question.

Lets use my calculator for instance. Using something it has designated K (for no apparent reason) I can enter a formula, such as K=*2-4, and after that is entered every number I then type and press equals to it will run that formula and spit out an answer. (after entering that function, if I press "5" "equals" it will give me "6") Now what I'm wondering is if excel has a "K" function that I can assign to certain cells, namely a column, so that whenever a figure is typed in any of the cells in that column, the required operation is done, namely *.9685.

Budget Worksheet - Lock Cells With Formulas

Jul 24, 2014

So I am trying to create a budget worksheet for past and future expenses, basically an excel checkbook with running balance

In Column A I have my debits/credits

In Column B I have my running balance so that there is a current total next to each of the debit/credits in column A, it is formulated as follows, it adds the cells directly above it to the cell directly to the left of it (i.e. Cell B10 = B9+A10, which was dragged and iterated to many cells below)

I wan to be able to drag in drop cells in the A column (Just moving them up and down different cells in the A column) with out it changing formulas in the B column.

I tried the $ trick so that for example B10 = B9+$A$10 but if I moved cell A9 to say A10, I get a reference error in cell B10 (why is it doing this when B10 is locked with $)

I then tried going to format and locking the B column and not the A column and then protected the document but I still get the same REF error.

I know I can copy and paste with out effecting it but this is tedious, the whole reason I did this was so that I can move around bills EASILY and play around with what get paid when. There has to be a way to do this, but I'm probably searching with the wrong keywords.

Worksheet Link Search And Fill Formulas

Jul 18, 2008

I want to create a spreadsheet table of values that are linked other spreadsheets, a condesnsed version... I am not a total amateur and I understand the world of excel links....

However the problem lies in the fact that the source files change format every day, what i need is a formula for each cell (i know...) that can:

1. Firstly find column and row heading titles by looking for part of the title i.e. for a title like 'Occupation' i need a non case sensitive search for 'Occu'.

2. Once colum and row are found, return the intesecting value.

The formulas are needed so all I will have to do, after this is finished, is update the source files and the relevant numbers will be found automatically.

Im sure this is something that can be done with a clever array formula, setup to recognise column and row intersections based on positve returns on search variables, however this one is just outside my capabilities....

Formulas To Pull Data In Various Columns Within Row 2 Of Another Worksheet

Nov 10, 2011

I need some VBA code that puts in formulas to pull data in various columns within row 2 of another worksheet.

The formulas need to be entered below some other data, which is populated from another prior macro.

The below code works well but as the prior macro can populate a different number of rows on different days, the Row count then also changes and doesn't always refer to row 2 of 'HLDRT before' tab.

ActiveCell.FormulaR1C1 = _
"=IF('HLDRT before'!R[-22]C[-18] = ""A17"",RIGHT('HLDRT before'!R-20C[14],3)&'HLDRT before'!R-20C[9]&'HLDRT before'!R-20]C[-13],"""")"

Is there a way I can tell the above code to always use row 2 from the 'HLDRT before' sheet, while keeping the column number lookups the same?

I think there is a way to do it by removing the [] signs but I can't get it to work. I also then need the macro to copy these down so I'm not sure if using $ will cause problems?
